About the Institute | 关于本机构

Independent Technical Research Institute for Aluminium Recycling Technology
独立再生铝技术专业研究机构

1. Operational Boundaries

We hold that independence is established by auditable operational boundaries rather than by declarations of neutrality. Three enforceable principles govern everything we publish:

Boundary	Operational Mechanism
Zero Equipment Agency 不做设备销售代理	The institute does not act as sales representative, distributor or commission-based agent for any manufacturer of dross presses, rotary furnaces, dross coolers, filtration systems or casting moulds.
Zero Paid Rankings 不承接商业推广排名	We do not accept compensation to feature, rank or promote equipment vendors, third-party recyclers or proprietary brands within comparative studies or benchmarks.
Zero Conditioned Funding 不接受影响结论的资助	We do not accept grants, advertising spend or corporate sponsorship that stipulate, modify or restrict the conclusions, data or technical verdicts of published work.

2. Scope of Work

The institute’s work falls into four defined domains. Each published item is assigned to at least one of them:

• Process Documentation — Systematic description of dross formation, thermal recovery, salt slag treatment and residue valorisation routes, with reaction mechanisms stated explicitly.
• Equipment Evaluation — Structural and performance analysis of casthouse equipment (dross presses, coolers, pans, sow moulds, degassing and filtration units), organised around measurable parameters rather than brand claims.
• Regulatory Mapping — Comparison of how the same material stream is classified and regulated across jurisdictions, including hazardous waste catalogues and cross-border transfer rules.
• Patent & Historical Tracing — Retrieval and analysis of landmark patent families and engineering history, cited by publication number, filing date and applicant.

3. Data Sources & Verification Standard

All quantitative parameters, reaction equations, thermodynamic values and trade figures published by the institute are drawn exclusively from verifiable public sources:

• Peer-reviewed literature & symposia — Proceedings of The Minerals, Metals & Materials Society (TMS Light Metals), European Aluminium, and international metallurgical conferences.
• Customs & trade repositories — Records filed under the Harmonized System codes listed below, together with United States Geological Survey (USGS) mineral statistics.
• Patent registries — Original texts retrieved from WIPO Patentscope, USPTO, Espacenet/EPO and Google Patents.
• Regulatory frameworks & corporate filings — EU Waste Framework Directive, US EPA guidance, China’s National Hazardous Waste Catalogue, and audited annual disclosures of publicly listed smelters.

3.1 Trade Classification Anchors

The institute uses these HS codes consistently across all trade-related content:

HS Code	Commodity	中文品名
2606.00	Bauxite, ores and concentrates	铝矿砂及其精矿
7601.10 / 7601.20	Unwrought aluminium — non-alloy / alloy	未锻轧铝（非合金 / 铝合金）
7602.00	Aluminium scrap	铝废碎料
2620.40	Slag, ash and residues containing mainly aluminium (incl. skimmings and aluminium ash)	主要含铝的矿渣、矿灰及残渣（含扒渣、铝灰）

3.2 Hazardous Waste Classification (China, HW48)

Under the National Hazardous Waste Catalogue (2025 Edition), aluminium-bearing residues fall under category HW48 — non-ferrous metal mining and metallurgical wastes. The codes relevant to this site:

Waste Code	Description	Hazard
321-024-48	Dross from melt transfer, refining, alloying and casting in primary aluminium, plus salt slag and secondary dross from aluminium recovery	R, T
321-026-48	Dross from remelting, refining, alloying and casting of scrap and ingots in secondary aluminium and fabrication, plus salt slag and secondary dross	R
321-034-48	Dust collected by dedusting units treating flue gas from thermal dross recovery, aluminium smelting and secondary melting	T, R
321-023-48	Spent pot lining from electrolytic cell maintenance and replacement (not dross)	T
321-025-48	Carbon residue from primary aluminium production (not dross)	T

Hazard codes: R = Reactivity (反应性), T = Toxicity (毒性). Source: 生态环境部等五部门《国家危险废物名录（2025年版）》.

4. Units, Terminology & Citation Standard

• Units — SI units throughout. Energy in kWh/t or MJ/t; temperature in °C with Kelvin noted where thermodynamically relevant; composition in mass percent.
• Terminology — Every abbreviation is given in full on first appearance, e.g. Tilting Rotary Furnace (TRF), Ceramic Foam Filter (CFF). Usage is then consistent across the site.
• Patents — Cited by publication number, applicant and publication date. Machine-translated claims are used for comprehension only and are never quoted as original text.
• Unverified data — Where a figure cannot be traced to a primary source, it is marked unverified rather than presented as established.

5. Corrections Policy

Technical accuracy is maintained through open correction rather than silent revision:

• Reporting — Errors, outdated figures or missing citations may be submitted to the research board at any time.
• Assessment — Substantiated reports are assessed against the primary source; the outcome is communicated to the submitter.
• Transparency — Substantive corrections to published data are recorded on the page with the date of revision, so that readers can see what changed and when.

6. Non-Endorsement Policy

Within the historical engineering archive (Patents & Pioneers), biographies of key figures and technical breakdowns of historical equipment serve strictly as factual, chronological documentation of technological progress. The institute does not issue commercial awards, supplier endorsements or vendor rankings.

机构定位与使命

AluminiumRecycling 的定位是一家专注于铝回收技术的独立技术研究机构（An independent technical research institute for aluminium recycling technology）。机构致力于全球原铝与再生铝铸造车间（Casthouse）领域的技术文献整理、冶金工程分析、装备性能评估与环保法规梳理。

我们的核心宗旨是为全球铝厂冶金工程师、车间主管、环保合规人员及学者，提供清晰、严密、可查证且基于热力学原理的技术文档。

1. 可核查的独立性：三大行为边界

我们认为，真正的独立性应当建立在可核查的运行边界之上，而非空洞的立场宣示。为确保所有已发表报告与技术对比的客观性，本研究机构严格恪守以下三项行为边界：

行为边界	执行机制
1. 不做设备销售代理	本研究机构不作为任何铝渣压榨机、回转炉、冷却器、过滤系统或铸模制造厂家的销售代表、渠道分销商或佣金代理人。
2. 不承接商业推广排名	我们不接受任何形式的商业付费，不在技术对比、行业报告或装备评估中为特定设备商、第三方回收商或商业品牌提供付费排名或赞助推广。
3. 不接受影响结论的资助	我们不接受任何附带条件（规定、修改或限制研究数据与技术结论）的商业资助、广告投放或课题赞助。

2. 工作范围

本机构的工作分为四个领域，每项发布内容至少归入其中之一：

• 工艺文献整理 —— 系统描述铝渣生成、热态回收、盐渣处理与残余物资源化路线，明确写出反应机理。
• 装备性能评估 —— 对车间装备（压榨机、冷渣机、渣锅、锭模、除气与过滤装置）做结构与性能分析，以可测量参数而非品牌宣传为组织依据。
• 法规映射 —— 比较同一物料流在不同法域的分类与监管方式，含危险废物名录与跨境转移规则。
• 专利与历史溯源 —— 调阅并分析里程碑专利族与工程史，按公开号、申请日、申请人逐条引用。

3. 数据来源与核验标准

本机构发布的所有定量参数、化学反应方程式、热力学数值及贸易数据，均严格引自可查证的公开领域：

• 同行评审学术文献 —— 美国 TMS 协会《Light Metals》研讨会论文集、欧洲铝业协会（European Aluminium）及国际冶金会议记录。
• 海关与贸易数据库 —— 上表所列协调制度编码下的全球贸易记录，配合美国地质调查局（USGS）统计数据。
• 知识产权注册库 —— WIPO Patentscope、USPTO、Espacenet/EPO 及 Google Patents 调阅的原始专利文本。
• 环保法规与上市公司公开披露 —— 欧盟废弃物框架指令、美国 EPA 指南、《国家危险废物名录（2025年版）》，以及全球上市铝企经审计的年度报告。
